Driving in a slow car [Wiki entry]

An insatiable appetite for fuel has been a primary reason for countless wars - disguised, of course, as the good "fight for democracy". Several alternative energy sources are dismissed as being too "inefficient"to be of any practical use. However, as this wikipedia entry suggests, about a hundred years ago, rechargeable battery operated cars ran upto a mind-boggling 340km on a single charge, while 130km per charge was guaranteed. Granted, top speed was 20km, but adequate for city driving (have you been in a fast moving traffic jams that is ubiquitous the world over?). It's a bit hard to believe that despite all progress, there are no commercially viable batteries, after 100 years! Or maybe it is so by choice?
